  17. Install a commercially available bearing separator (D) on the gearbox housing. Set the steering gearbox in a press so the gearbox housing points upward, then push out the cylinder end seal (E) 5-6 mm (0.200.24 in.) by pressing on the 24" long 3/8" drive extension end.
  18. Remove the steering gearbox from the press, and remove the washer from the gearbox.
  19. Turn the special tool so it will fit through the rack guide hole of the steering gearbox, then position the special tool on the cylinder end seal (A). Make sure that the special tool is securely positioned on the seal edges.

  20. Insert a 24" long 3/8" drive extension (A), on the special tool. Place the steering gearbox in a press, then remove the cylinder end seal (B) from of the gearbox by pressing on the 24" long 3/8" drive extension.

    Note these items when pressing the cylinder end seal:

    • Keep the tool straight to avoid damaging the cylinder wall. Check the tool angle, and correct it if necessary, when removing the cylinder end seal.
    • Use a press to remove the cylinder end seal. Do not try to remove the seal by striking the tool; striking the tool would break the cylinder end seal, and the seal would remain in the gearbox.
